: Low-latency interrupt response times calculated to an exact number of clock cycles.
Pins like BOOT0 and BOOT1 dictate where the CPU fetches its first instruction upon reset. Grounding BOOT0 forces the chip to boot from user Flash memory. Pulling BOOT0 high boots the chip into the system memory, activating the factory-programmed bootloader for serial flashing. 4.

Modern ARM development heavily relies on Serial Wire Debug (SWD) due to its minimal pin overhead compared to traditional JTAG. Where to Find the Book
Leo looked at his desk. The chaos was still there, but the confusion was gone. He had moved from a "copy-paster" to a builder.
